Cov iav tempered ib txwm muaj qhov tshwm sim ntawm qhov tawg ntawm ib ncig ntawm peb ntawm ib txhiab.Nrog kev txhim kho hauv qhov zoo ntawm cov iav substrate, tus nqi no yuav txo qis.Feem ntau, "spontaneous breakage" yog hais txog cov iav tawg yam tsis muaj kev quab yuam sab nraud, feem ntau ua rau cov iav shards ntog los ntawm qhov siab siab, ua rau muaj kev phom sij loj.
Cov yam ntxwv cuam tshuam txog kev tawg ntawm cov iav Tempered
Spontaneous breakage nyob rau hauv tempered iav tuaj yeem raug ntaus nqi rau sab nraud thiab sab hauv.
Sab nrauv yam ua rau iav tawg:
1.Ntug thiab Ntog Xwm Txheej:Kos, nto corrosion, tawg, los yog tawg npoo ntawm lub iav nto tuaj yeem ua rau muaj kev ntxhov siab uas yuav ua rau muaj kev tawg.
2.Gap nrog Frames:Cov qhov khoob me me lossis kev sib cuag ncaj qha ntawm cov iav thiab cov thav ntawv, tshwj xeeb tshaj yog thaum lub hnub ci hnyav, qhov sib txawv ntawm qhov sib txawv ntawm cov iav thiab hlau tuaj yeem tsim kev ntxhov siab, ua rau cov ces kaum iav yuav compressed los yog ua rau lub thermal stress ib ntus, ua rau iav tawg.Yog li ntawd, kev txhim kho kom zoo, suav nrog cov roj hmab sealing kom zoo thiab tso cov iav kab rov tav, yog qhov tseem ceeb heev.
3.Drilling los yog Beveling:Tempered iav uas undergoes drilling los yog beveling yog yooj yim rau spontaneous breakage.Zoo tempered iav undergoes ntug polishing kom txo tau qhov kev pheej hmoo no.
4.Cua Siab:Hauv cov cheeb tsam uas muaj cua daj cua dub los yog hauv cov tsev siab, kev tsim tsis tsim nyog los tiv thaiv cua tuaj yeem ua rau muaj kev tawg thaum muaj cua daj cua dub.
Internal Factors uas ua rau iav tawg:
1.Pom tsis zoo:Pob zeb, impurities, los yog npuas nyob rau hauv lub khob tuaj yeem ua rau muaj kev ntxhov siab tsis sib xws, ua rau muaj kev tawg.
2.Iav Invisible Structural Defects, Ntau dhau impurities ntawm npib tsib xee sulfide (NIS) kuj tuaj yeem ua rau iav tempered rau nws tus kheej vim tias muaj cov nickel sulfide impurities tuaj yeem ua rau muaj kev ntxhov siab sab hauv hauv iav, ua rau muaj kev tawg.Nickel sulfide muaj nyob rau hauv ob theem crystalline (high-temperature phase α-NiS, low-temperature β-NiS).
Nyob rau hauv lub tempering rauv, ntawm qhov kub thiab txias ntau dua li theem hloov kub (379 ° C), tag nrho cov nickel sulfide hloov mus rau hauv high-temperature α-NiS.Lub khob sai sai txias los ntawm qhov kub thiab txias, thiab α-NiS tsis muaj sijhawm los hloov mus rau β-NiS, khov rau hauv cov iav tempered.Thaum cov iav tempered tau teeb tsa hauv cov neeg siv khoom lub tsev, nws twb nyob hauv chav tsev kub, thiab α-NiS nyiam maj mam hloov mus rau β-NiS, ua rau 2.38% ntim nthuav dav.
Tom qab iav dhau los ntawm tempering, qhov saum npoo tsim compressive kev nyuaj siab, thaum sab hauv pom muaj zog tensile.Ob lub zog no nyob rau hauv qhov sib npaug, tab sis qhov ntim nthuav dav tshwm sim los ntawm kev hloov pauv ntawm cov nickel sulfide thaum lub sij hawm tempering tsim muaj zog tensile kev nyuaj siab nyob ib puag ncig.
Yog tias cov nickel sulfide no nyob hauv nruab nrab ntawm lub khob, kev sib xyaw ntawm ob qhov kev ntxhov siab tuaj yeem ua rau cov iav tempered rau nws tus kheej puas tsuaj.
Yog hais tias npib tsib xee sulfide nyob rau hauv lub iav nto nyob rau hauv lub compressive cheeb tsam, tempered iav yuav tsis self-destructed, tab sis lub zog ntawm tempered iav yuav txo.
Feem ntau, rau cov iav tempered nrog ib tug nto compressive kev nyuaj siab ntawm 100MPa, ib tug npib tsib xee sulfide nrog ib txoj kab uas hla ntau tshaj 0.06 yuav ua rau nws tus kheej puas tsuaj, thiab hais txog.Yog li ntawd, xaiv qhov zoo raw iav chaw tsim tshuaj paus thiab iav fabrication txheej txheem yog ib qho tseem ceeb heev.
Kev tiv thaiv kev daws teeb meem rau kev sib tsoo tawg hauv Tempered iav
1.Xaiv tus Reputable Glass Chaw tsim tshuaj paus:Cov qauv iav, kev tsim cov txheej txheem, thiab cov khoom siv tempering tuaj yeem sib txawv ntawm cov float iav factories.Xaiv rau cov chaw tsim khoom lag luam txhim khu kev qha kom txo tau qhov kev pheej hmoo ntawm kev tawg.
2.Tswj iav Loj:Cov iav tempered loj dua thiab cov iav thicker muaj cov nqi siab dua ntawm kev tawg.Ua tib zoo xav txog cov xwm txheej no thaum xaiv iav.
3.Xav txog Semi-Tempered iav:Semi-tempered iav, nrog txo cov kev ntxhov siab sab hauv, tuaj yeem txo qhov kev pheej hmoo ntawm kev tawg.
4.Xaiv rau Uniform Stress:Xaiv cov iav nrog txawm tias muaj kev ntxhov siab thiab qhov chaw du, vim kev ntxhov siab tsis sib xws ua rau muaj kev pheej hmoo ntawm kev tawg.
5.Kev Ntsuas Kub Soak:Cov iav tempered rau kev ntsuas sov so, qhov twg lub iav yog rhuab kom nrawm rau theem hloov ntawm NiS.Qhov no tso cai rau muaj peev xwm ua kom tawg tau tshwm sim hauv qhov chaw tswj hwm, txo qhov kev pheej hmoo tom qab kev teeb tsa.
6.Xaiv Low-NiS iav:Xaiv cov iav ntshiab, vim nws muaj tsawg dua impurities zoo li NiS, txo qhov kev pheej hmoo ntawm kev tawg.
7.Thov Kev Nyab Xeeb Zaj Duab Xis:Txhim kho qhov tawg-pov thawj zaj duab xis rau sab nrauv ntawm lub iav kom tiv thaiv iav shards los ntawm kev poob thaum muaj kev tawg.Thicker films, xws li 12mil, raug pom zoo rau kev tiv thaiv zoo dua.
